SFB 1242 „Non-equilibrium dynamics of condensed matter in the time domain"
States of non-equilibrium can be created in condensed material through ultra-rapid external stimuli such as light, pressure, electrical voltage or particles. This Collaborative Research Centre aims to achieve a cross-material, microscopic understanding of such non-equilibrium states. To this end, new methods in experimental and theoretical physics will be developed to describe the process from the moment of the stimulus to a state close to equilibrium in time and space.
SFB 1093 "Supramolecular Chemistry on Proteins" (seit 2014)
Protein function is intimately connected with supramolecular chemistry: Substrate processing and various levels of regulation involve specific noncovalent interactions. Likewise, protein folding, assembly and protein-protein interactions are governed by intermolecular forces and their specific inhibition or support represents a very promising area for external interference, with profound mechanistic and therapeutic implications.
The CRC aims at applying recent knowledge and methods from supramolecular chemistry to achieve specific interaction with proteins by artificial ligands.

SFB 616: Energy Dissipation at Surfaces (2002-2013)
The transformation of energy from one form to another is an integral part of all day-to-day processes, and frequently propels these processes also. Many of these transformations – such as chemical reactions involving catalysts or sensors, mechanical friction, or the dispersion of charge carriers in microprocessors – take place at surfaces or at the interfaces of solid materials. The associated dissipation of energy, i.e., the distribution into various channels of the energy form that is entered primarily into the surface comprises, from a microscopic perspective, a sequence of energy transfer steps between the various electronic and vibronic degrees of freedom of the system, at the end of which the energy is displaced in such a way that the result is an increase in temperature and possibly material changes. The aim of the collaborative research center is to clarify the elemental processes involved in energy dissipation at surfaces. The program is broadly designed overall and encompasses the entire spectrum of excitation and relaxation from the eV area (laser excitation, reaction at surfaces) through to lattice vibrations and friction losses down to the meV area (electromigration).
SFB 491: Magnetic Heterostructures: Spin Structure and Spin Transport (2000-2011)
Heterolayer structures are artificially layered materials separated by well-defined interfaces in the nanometer range with new types of physical properties. The objective of SFB 491 is to work out the physical fundamentals of such heterolayer systems, which offer great potential in various areas of information and communication technology, particularly in the field of non-volatile data storage, magnetic field sensor technology, and the management of future data media. SFB 491 involves close collaboration between the approximately 50 researchers from the working groups at the Ruhr University Bochum, the University of Duisburg-Essen and the Jülich Research Center.
SFB 445: Nanoparticles in the Gas Phase (1999-2010)
In SFB 445, researchers from the University of Duisburg-Essen working in the fields of physics, mechanical engineering, chemistry and electrical engineering are conducting experimental and theoretical research into new types of nanomaterial. Fifty researchers are investigating the targeted synthesis of highly defined nanomaterials in the gas phase, as well as their physical characterization. One area of focus is to relate particle structure and particle properties to each other with the ultimate aim of opening up new applications in electrical engineering, sensor technology, and catalysis. The collaborative research center is therefore successfully establishing ties between basic research and application-oriented research.
